[58] The hosts on the show tried a series of frequencies as low as 5Hz, attaining a level of 120decibels of sound pressure at 9Hz and up to 153dB at frequencies above 20Hz, but the rumored physiological effects did not materialize.

Work by Muggenthaler et al, referred to in: David Harrison: von Muggenthaler, (2006) The Felid Purr: A Biomechanical Healing Mechanism, Proceedings from the 12th International Low Frequency Noise and Vibration Conference, pp. For instance, in 1972, Borredon exposed 42 young men to tones at 7.5Hz at 130dB for 50 minutes. The study of such sound waves is sometimes referred to as infrasonics, covering sounds beneath 20Hz down to 0.1Hz (and rarely to 0.001Hz). The microphone features a high membrane compliance with a large backchamber volume, a prepolarized backplane and a high impedance preamplifier located inside the backchamber. We talk about many good products on this website and all the readers love it.
